To provide a vehicle pollution inspection system capable of performing pollution inspection of a vehicle going out of a radioactive material handling facility in a short time.SOLUTION: The vehicle pollution inspection system comprises gate type unit 1 provided with a first detector 3A, a second detector 3B and a third detector 3C which have the same dimension and function as a controller 30. After measuring a width dimension W between a first side plate 22A and a second side plate 22B of a loading platform 21 by a measuring unit 6, and after confirming that the relation between a width dimension B and a width dimension W of the detector is 1.5×B<W<2×B by a calculation unit 32, an overlapping distance BC1 of the first detector 3A and the second detector 3B is calculated. Under this arrangement relation, the first detector and the second detector are run from a front plate 23 to a rear plate 24 of the loading platform 21, radiation is detected by a radiation detection unit 12, whether or not it is within a permissible value is determined by a determination unit 34, and a result is displayed on a second display unit 35 of the control device 30 and a first display unit 7 of the gate type unit 1.SELECTED DRAWING: Figure 1 【課題】放射線物質取扱施設外に出る車両の汚染検査を短時間に実施可能な車両の汚染検査システムを提供する。【解決手段】制御装置３０と同一寸法、同一機能を有する第一検出器３Ａ、第二検出器３Ｂ、第三検出器３Ｃとが設けられた門型ユニット１を備え、荷台２１の第一側板２２Ａと第二側板２２Ｂとの間の幅寸法Ｗを測定部６が測定後、検出器の幅寸法Ｂと幅寸法Ｗとの関係を演算部３２で１．５×Ｂ＜Ｗ＜２×Ｂであることを確認後、第一検出器３Ａと第二検出器３Ｂの重複距離ＢＣ１が算出され、その配置関係で荷台２１の前面板２３から後面板２４まで走行、放射線検出部１２で放射線を検知、判定部３４で許容値内か否か判定され、その結果が制御装置３０の第二表示部３５、門型ユニット１の第一表示部７に表示される。【選択図】図１
